Page 5: Introduction
Introduction The SOLO4 Bodywire Transmitter is a COFDM digital video transmitter, designed specifically for covert video installations and body worn applications. The small size and low power consumption of the SOLO4 Bodywire make it the product of choice for covert video hides, or applications requiring long term battery power deployments, small unmanned aerial vehicles, and body worn or body wire use. -
Page 6: Warranty And Support
Warranty and Support 1.1 Warranty Cover domo offers a 12 month standard product warranty. During this period, should the customer encounter a fault with the equipment we recommend the following course of action: • Check the support section of the website for information on that product and any software/firmware upgrades. -

SOL4MTX-200250 SN 123456 Made in the UK The domo product code can be referenced in the table below. Product Code Product Accompanying items SOL4MTX-100150 (1.0 to 1.5GHz) 100mW Digital Cables: Video Multi-way break out cable. transmitter LBand 12V DC cable 3m Blank Dtype mating connector for user integration. -
Page 10: Controls
Controls The SOL4MTX has no local control panel or indicators. The SOL4MTX is controlled by connecting a local PC and using the domo PC control GUI application, or alternatively by using the separate domo ‘Field Gun’ controller. The use of the domo PC GUI application is described fully in section 3 ‘Advanced Operation’. - Page 11 The domo transmitter is supplied with the following cables. • CA0317 Break out Cable, the drawing of this cable is shown below. • CA0002 lemo to banana plug 12V cable There are 4 ways to connect to the SOLO4 Bodywire transmitter, depending on the application.
- Page 12 Option 4. Cut off the 15 way DType Male connector, and wire direct to the cables. Each option is explained in detail below. Option 1. Using the CA0317 Break Out Cable The CA0317 cable is terminated with a 15 way DType female connector and this plugs directly to the 15 way DType Male connector on the SOLO4 Bodywire transmitter.

- Page 16 Antennas domo transmitters are supplied as standard without antennas. An antenna must be connected for normal operation. The transmitter unit is supplied with a panel mounted SMA connector which carries the RF output. The antenna should be connected by screwing it onto the SMA, but care should be taken to not over tighten the connector.

- Page 18 Cable length: 200mm 4.00 88.00 92.00 Integration in Covert Hides Users should be aware of the following issues when integrating the equipment in any covert hide. 1) Ventilation: The equipment does not require forced air cooling, but ideally should be mounted to a metal surface for cooling effect. Ideally the low power 50mW mode should be employed to reduce the consumed power.
- Page 19 4) The antenna should be mounted vertically ideally, and exposed to free space. 5) The equipment should be supplied with a clean supply in the range 5.9 to 16V and capable of 0.4A maximum. Care should be taken to avoid direct supply from the vehicle 12V which can be very noisy. Power conversion will be required for 24V vehicles.
- Page 20 The SOLO4 Bodywire transmitter has been successfully tested with a wide variety of standard and pinhole cameras. domo can supply cameras on request. The domo transmitter will become warm to the touch after prolonged operation, and so insulation between the operators’ body and the transmitter unit should be considered.

Page 21: Powering On The System
Powering on the System All external connection to the SOLO4 Bodywire transmitter should be made, as described in the previous sections, before proceeding to power on the system. Users should ensure that a suitable receiver is available and configured to the appropriate frequency before proceeding with the remainder of this chapter (see handbook for the SOLO4 receiver or SOLO4 MicroVue) Apply power to the transmitter... -

The displayed diagnostic data includes a spectrum display, signal to noise data, input power level and frequency. The received spectrum display is useful when checking for interference signals, the SNR indicated signal quality. For more information on use of this facility a domo training course is recommended. - Page 23 Using the SOLBAT The domo SOLBAT is used for powering domo transmitters. The domo SOLOBAT can not be connected directly to the Bodywire Transmitter, instead it must be connected using the SOLBCC adaptor cable. The SOLBCC adaptor cable provides an interface between the 4 pin DC In Lemo on the CA0317 transmitter break out cable and the 6 pin DC Out Lemo on the battery.

Page 26: Using The Booster 5W Amp
Installation Notes The domo SOLAMP has been designed specifically for vehicle applications, however it is a general-purpose amplifier and can be used in many applications including the following. • Vehicle applications • Aircraft applications • Long Range fixed links Interconnection between the SOLAMP transmitter and the antenna, or any intermediate optional power amplifier should be kept as short as possible. - Page 27 DC Power Cable • RF Connection The domo AMP5W has the following input power requirements. AMP5W-115140: Input Power 100mW or 20dBm AMP5W-225255: Input Power 100mW or 20dBm Therefore care must be taken when connecting the AMP5W-225255 product to the SOLO4 Bodywire transmitter. Ideally when balancing the 5W Amplifier and domo transmitter a power meter should be employed, this will give best results, because cable losses can be factored.
